What Makes Survival Garden Seeds Different - non-GMO heirloom seeds

Grow fresh, crisp radishes in just a few weeks with Champion Radish Seeds from Survival Garden Seeds. This trusted heirloom variety (Raphanus sativus) produces bright red, round roots with tender white flesh and mild flavor—perfect for salads, sandwiches, or snacking straight from the garden.

Champion radishes are known for their fast germination, reliable performance, and adaptability across seasons. They thrive in both cool spring weather and warmer fall conditions, making them a go-to choice for gardeners who want consistent results and an extended harvest window.

Quick, Productive, and Flavorful:

  • Fast-growing heirloom: Ready to harvest in about 25 days.
  • Crisp and mild: Smooth, bright red globes with tender white interiors.
  • Versatile grower: Performs well in both spring and fall, with better heat tolerance than many radish varieties.
  • Dependable results: Suitable for beginners and experienced gardeners alike.

Why Customers Love Champion Radishes:

  • Quick rewards from seed to harvest.
  • Great balance of size, flavor, and crunch.
  • Consistent yields even in variable weather.
  • Non-GMO, open-pollinated, and quality-tested in the USA.

How to Grow:

Sow directly into well-prepared soil as soon as it can be worked in spring, or again in late summer for fall harvests. Plant seeds about ½ inch deep and 1 inch apart in rows 8–12 inches apart. Thin seedlings to allow roots space to develop properly. Keep soil evenly moist for the best texture and flavor. Harvest when roots are 1–2 inches across for optimal crunch and sweetness.

For a steady supply, sow every couple of weeks throughout the growing season. Champion’s resilience and heat tolerance help extend your planting season—ideal for gardeners who enjoy fresh produce from early spring through late fall.

    Sow outdoors in sunny well-drained soil. Radishes are best planted in spring or fall. If your radishes get too hot they will lose their flavor and go bitter. Radishes can also be planted indoors with enough light.
  • Seed Saving Instructions
    Wait until a few of your radishes flower and wilt. At that point, the seed pods will form. Once those have dried and the seeds rattle inside of them, clip off the pods then remove and store the seeds dry.
